    // TODO: Migration - most probably all subscriptions should have their items set to existing products BEFORE migration takes place and we should provide a tool to link items to products on site
    // TODO: possibly change from post_type="subscription" to post_type="rp_sub_subscription" and write a separate old data retrieval method
    // TODO: possibly change from post_type="sub_transaction" to post_type="rp_sub_log_entry" and write a separate old data retrieval method
    // TODO: Ensure plugin settings and object data are not overriden if old settings or object page is submitted after the update (opened before update)
    // TODO: Shouldn't we ensure that only one updater is running and not a few of them accidentally? Also, need a way to safely run migration of bigger data sets that may cause timeout/memory issues (e.g. Stripe migration problems).
    // TODO: When migrating, check all date fields for this issue https://github.com/RightPress/subscriptio/issues/319
    // TODO: Copies of settings, objects, data as they were before migration https://github.com/RightPress/subscriptio/issues/393
    // TODO: Must fill last_renewal_order_id for all subscriptions with renewal orders when migrating to 3.0
    // TODO: Previously we allowed manual scheduled event date changes - need to account for that when migrating
    // TODO: Migration script should check if everything is ready, e.g. Stripe extension installed or so.
    // TODO: Incorporate Stripe migration (if not migrated yet) into the main migration process, separate migration script is not in the new version (include source/customer retrieval from all possible locations)
    // TODO: Need to import scheduled actions from old schedulers (we had one current and one legacy)
    // TODO: Migrate main site url (old subscriptio_main_site_url, new rp_sub_main_site_url; old subscriptio_ignore_url_mismatch, new rp_sub_ignored_mismatch_url)
    // TODO: Migrated email enabled state and email settings
    // TODO: Migrate product settings, including "Subscription" checkbox key in database (was '_subscriptio', now '_rp_sub:subscription_product')
    // TODO: Before migrating, check if new version has never run on the same site (e.g. check for presence of settings or subscription records in database) as this could become messed up
    // TODO: Need to consider data under _subscriptio_pause_limit in user meta for pause_limit_reached()
    // TODO: If we used to grant file access to subscribers in a different way, need to fix this during migration
    // TODO: Need to check old _subscriptio_trial_product_ids during subscriptio_customer_is_eligible_for_trial
